OB will not even attempt to start after sitting for a day or so. I have tried every possible variation of cold start process suggestions I could find, and none make a difference. After awhile, it seems to just pop and fire for no rhyme or reason. Once its started it seems to run, and start back up without a problem. (On the muffs, I haven't gotten a change to take it out yet, im not confidant it wont leave me stranded)
Sounds a little raspy when it idles, but I'm not sure if that's normal or not, this is my first 2T outboard.
Compression is between 95-100 on all holes..
New fuel, new primer bulb. electric fuel primer system is working perfectly.
New battery, spins the ob at ~500rpm no problems there. Even ran jumper cables to eliminate possible cabling issue.
New plugs, champion gapped at .030. They get oily/wet looking, but I am only running it at idle/ slightly above as I am on the hose.
checked the keyswitch per the process in the book, seems to be working ok.
checked the shift switch, just disconnected it, no difference.
Once it starts and runs, checked the timing with a light and seems to be right on spec. TDC also correct.
Onto the spark test...
Well, got a cheap $12 tester, set the gap to 12mm, clamped it to a headbolt & grounded all of the other leads to the head as the manual suggested
I get intermittent spark across all holes at that gap. Sometimes it will fire 2-3-4 in a row then nothing for another 3-4-5 revolutions. Pretty consistant across all holes, makes me wonder if I am doing it right, or if the tool is working correctly.
When I close the gap down to 4-5mm or so, it fires every time.
Will take a look at further troubleshooting tomorrow.. The book didn't really state anything for intermittent spark, just no spark or spark on certain banks/pairs ect. any suggestions ?
I will take a peek through the remaining components and see what I can test without special tools (I dont have a peak voltmeter etc).. At this point, unless I can find something obviously wrong I wonder if it would be cheaper in the long run to take it in
